Article
Castel di Casio (Medial Mountain Bolognese: Castèl or Castèl d Chèsi) is a comune (municipality) of the Metropolitan City of Bologna in the Italian region Emilia-Romagna, located in the Bolognese Apennines, about 60 kilometres (37 mi) southwest of Bologna. It lies in the valley of the Limentra stream, between the basin of Lake Suviana and the confluence of the Limentra with the Reno river.
In the Middle Ages Casio was one of the principal centres of Bolognese authority in the Apennines. In the early 13th century it was transformed by the Comune of Bologna from an open village into a fortified castle, and later became the seat of the podestà and of the Capitani delle Montagne ("Captains of the Mountains"), the officials through whom Bologna governed its mountain territory.
